| Abstract: | A detailed analysis was carried out of the requirements of the driving timing sequence of the progressive scan interline CCD KAI-0340 produced by Kodak Company. The programmable logic device(FPGA)of Altera Company was used for designing CCD driving timing sequence, which could enable the use of software in the designing of hardware circuit and improve development efficiency because the software was reprogrammable and modifiable. Results of experimental simulation showed that the designed sequence could meet the demand of the CCD KAI-0340. |
